Sony teases PSP announcements

Sony has promised that a host of key PSP titles will be announced before Christmas.

According to its director of hardware marketing John Koller, a range of new titles will be released in 2010 to mark the handheld platform's five year anniversary.

"As we move further into 2010, the innovation and technological prowess of the PSP system continues to be evident," he said.

"We have a plethora of exciting new games, some of which have yet to be announced, coming later this year that will continue to deliver the same unparalleled gaming experiences that you know and love."

Koller's comments echo statements from Rob Dyer, who previously teased significant PSP developments from third-party studios. Sony is expected to unveil new software for the system at this year's E3.

The PSP celebrated five years on the market this week, having made its debut in the US in March 2005. It has sold over 17 million units in the territory to date.
